Col de Joux Plane from Morzine in the Haute Savoie
Col de Joux Plane is situated in the Chablais and links the town of Morzine to the north with Samoens to the south.
After a challenging but picturesque first couple of kilometres which exceed 10%, the climb settles in to a steady 9% (!) in and out of forest all the way to the col du Ranfolly.
The road descends for a kilometre before the final kick up to the col de Joux Plane and a spectacular view over Mont Blanc.
The Tour de France crossed the col for the first time in 1978 and a further 10 times since then. The 2016 Tour de France crosses it for a twelfth time in its history.
